+ added parameter BreakIndex (containing the breakpoint index if we stopped on a

  breakpoint, or zero otherwise) to DoSelectSourceLine, instead of using
  stop_breakpoint_number
- removed stop_breakpoint_number and all the convoluted logic around it from the
  gdb/mi interface
* made stop_breakpoint_number private in the libgdb.a interface to ensure it's
  only used for internal use; UI code should rely on the new BreakIndex
  parameter instead
